    HONE. tlie s|>4>k(' «»f a wliccl, is the external bone lyin;^- pai-allel with the uhia when tlie pahn of the liand is turned up- ward. It re.seinbles other lon;^ bones in having- a shaft and two extremities. The up- ])vv or lesser extremity forms only a small portion of the elbow-joint, while the low^er extremity, which is hroad, forms the wrist by articulat- ing^ with two of the carpal or wi'ist bones. The lower end also articulates with the cor- responding portion of the ul- na. The shaft of the radius is more or less irregular and rough for the origin and in- sertion of muscles. The ease with which the forearm and hand may be turned with the palm down ( pronation ), and with the palm up (su- pination ''), is due to the pe- culiar articulation of the up- per end of the radius with the ulna. The upper end of the radius (or head) is somewhat knob-shaped, with a depression or excavation on its upper surface; the excavation artic- ulates with a small portion of the lower extremity of the humerus, and represents the limited part it takes in the formation of the elbow-joint. 15 Trochlea.
